Used with Siemens Fire Safety fire alarm control panels (FACPs), the Distributed Power Supply Unit Siemens PAD-3 (599-699189) is a NAC expander with a built-in auxiliary power output.
Each unit is designed to provide additional power for visual indicators in buildings that conform to the Americans with Disabilities Act (ADA).
Each Model PAD-3-series unit provides the following physical characteristics:
- NACs.
- Unit enclosure.
- Signal-input circuits.
- Battery-charging circuit.
- Trouble relays for remote monitoring.
- Diagnostic light-emitting diodes (LEDs).
- Alternating Current (AC) power connection.
The Siemens NACs, which connect with alarm signaling devices, have been designed to provide the highest reliability and performance.
Specifications Siemens PAD-3
Each Siemens PAD-3 unit provides 6A @ 24VDC power for multiple uses, and all 6 Amps can be directed to four (4) NACs. Each NAC is power-limited; and rated at 3A. Either one (1) or two (2) inputs can control the four (4) outputs.
These outputs are compatible with all Siemens Fire Safety 24VDC notification appliances. To make the outputs easily programmable, this version of the Siemens Auxiliary Power Supply (Model PAD-3) can be configured in the following manner:
- ‘STEADY’ outputs.
- Synchronized strobe outputs.
- American National Standards Institute (ANSI) Temporal 3.
